Although I did have a couple of students living on financial aid, who tried hard to get those referrals for me.So, I think you'd have to gauge your tenants and what amount would motivate them.  

Rip off the band aid lay down the law (rules) and see how it goes. 

I would not answer them or engage them in any way.I have had this happen to me a few times in the deep south even to the point of the free legal aid attornies writing me letters..

But, doing this, and being clear that this is their one and only one-time pass, put the kabash on asking me again.The only exception to that that I made, was for students who relied on their financial aid as their only source of income to pay the rent, etc.  

I give security deposit discounts to police, fire fighters, military, healthcare workers, and teachers.  

A couple of my student tenants were living on their financial aid, and I did let them pay rent late if their FA checks were running late (which I would get them to verify with a letter from the FA office).  

So, you don't have to give her any money back.Even if you take possession of the unit and accept keys - as long as you don't rent it to someone else, you can collect rent to the end of the lease.Page 27:http://www.georgialegalaid.org/files/6FCBD72D-B465...That's from Georgia Legal Aid, too, LOL.  

They were band-aided before I bought them.  

They also need health care and pensions, etc.So, what's next?  

I may ruffle a few feather with this blunt statement but get rid of them.Getting them out now is cheaper than spending $5,000 on legal aid and attorney fees six months from now when their water goes wrongs again.
